A homeowner in Baldwin called us on a Friday afternoon in December. Her heat had been acting up all week, running for a bit, then stopping. Some rooms warm, others cold. She’d already called one company that told her she needed a whole new boiler. Quote was over $8,000.
We came out the next morning. The problem was a stuck zone valve and a circulator pump that was starting to go. Total repair: under $600. The boiler had years of life left.
That’s the thing about heating system problems on Long Island. The symptoms can be confusing. Getting an accurate diagnosis, from someone who actually knows these systems, makes all the difference.
AJ Services has been repairing heating systems across Nassau County for over 20 years. We work on gas boilers, oil boilers, baseboard systems, and radiant heat, and we give you a straight answer about what’s actually wrong.
If you’re not sure what’s wrong, describe what you’re seeing — we’ll help you understand what it likely means.
Most Nassau County homes heat with a boiler. When something goes wrong, you want real diagnosis — not a push toward replacement.
We repair all major brands including Weil-McLain, Burnham, Peerless, Navien, Buderus, Slant/Fin, and Crown. We also work on older systems still running after 30+ years.
Before any repair, we explain the issue, the cause, and the cost. No work starts until you approve it.
AJ Services is a family-owned company based in Bellmore. When you call us, you’re dealing directly with the people who do the work — not a national chain.
We’re known for honest assessments. That Baldwin homeowner avoided an unnecessary $8,000 replacement because she called us for a second opinion.
